What is the city for? How can we make the invisible visible? What can we do with the data collected in our urban environments? How can it improve our lives?

Design is moving upstream. Dan Hill, a senior consultant and designer at Arup, argues that designers should no longer see themselves as 'problem solvers', rather they should be the people asking the right questions. He talks us through new urban design and how to sense our cities.

This talk was recorded live at COFA on October 15, 2010 as part of the free COFA Talks public lecture series.
